Exercise during pregnancy is good for baby later on

Chicago Parent staff

Pregnant women who exercise moderately in the second half of
pregnancy may reduce their child's risk of obesity for a
lifetime.

Remember that prenatal yoga you gave up on?
Here's a new reason to give it another try.

A University of Auckland study found that regular exercise
results in a slight reduction in a baby's birth weight. That's a
good thing, given that increased birth weight is associated with
greater risks of developing obesity later in life.

The study, published in the Journal of Clinical Endocrinology
& Metabolism, randomly assigned 84 pregnant women who were at
least 20 weeks along to either the non-weight bearing exercise
group or the control group. Women in the exercise group worked out
on a stationary bike for up to 40 minutes five times a week. They
did so until at least 36 weeks gestation.

Exercise had no effect on maternal body weight, but their
offspring were on average 143 grams lighter than the control group.
The study also tracked the maternal insulin resistance rate, which
is key in providing nutrients to the fetus, and found that it was
not significantly affected by exercise.
